My wife and I saw Amazing Spider Man 2 and Xmen DoFP in 3D recently. Spiderman was in a Imax and was quite impressive visually. Xmen was at a Real3D theater and was OK.
We are going to see HTTYD 2 on Saturday evening. I didn't even know EoT was in 3D until I read this thread, and apparently its in Imax, so I'll try and swing that too.
On the home front, There have been some really solid 3D films for free (with HBO/Starz) OnDemand. This month we watch Man of Steel, Pacific Rim, and Journey 2. All looked great streaming. Not all were written great . . .
